Low-Profile 180 W AC-DC Power Supplies Provide 94% Efficiency

XP Power has launched a new range of 180-Watt U-channel AC-DC power supplies that are intended for space-constrained medical (BF), industrial and IT applications. The low-profile devices are just 29.5 mm high and occupy a small 107.6 mm x 62.8 mm footprint, allowing them to be used in high-density designs. The units are suitable for Class I and Class II operation and offer 2 x MOPP (Means of Patient Protection) of isolation while delivering up to 94% efficiency.

The UCP180 series PSUs have an integrated 12 V, 500 mA fan output, eliminating the need for any external driver circuitry. When used in conjunction with a fan delivering 10 CFM airflow, they can deliver 180 W of power to a load – a power density of 14.2 W/in³. They are also suited for use in convection cooled applications where they deliver 120W (9.4 W/in³). The U-channel construction provides a robust housing, an optional cover is available for applications where the unit may be user-accessible.

Suitable for medical (BF) applications, the PSUs are approved to EN60601-1 and offer 2xMOPP of isolation (4kV) and low leakage current (50µA), making them suitable for use in BF applied part applications. Additional approvals including IEC60950-1-1 and IEC62368-1, and EMC performance that meets EN61000-4, make them suitable for a wide range of applications including ITE and industrial.

There are a total of seven variants offering single outputs of 12 V, 15 V, 18 V, 24 V, 28 V, 36 V and 48 V in the series. All devices have a universal input range of 85 to 264VAC and offer up to 94% efficiency while consuming <0.5W with no load. The operating temperature range is -40°C (-20°C for 180W load) to +70°C with no derating required below +50°C in either force cooled or conduction cooled applications.

The UCP180 is available from Allied Electronics, Digi-Key, element14, Farnell, Newark, RS Components, approved regional distributors, or direct from XP Power and come with a 3-year warranty.

1 W AC-DC Supplies Feature Ultra-Compact Packages

CUI’s Power Group today has announced the addition of two models to its PBO family of ultra-compact AC-DC power supplies. Outputting 1 W of continuous power, the open frame PBO-1 and PBO-1-B series are housed in vertical and right-angle SIP packages, respectively. The vertical PBO-1 series measures as small as 35 mm x 11 mm x 18 mm (1.38″ x 0.43″ x 0.71″), while the low profile, right-angle PBO-1-B series measures as small as 35 mm x 18 mm x 11 mm (1.38″ x 0.71″ x 0.43″), making them well-suited for industrial systems, automation equipment, security, telecommunications and smart home devices where limited board real-estate is a factor.
These high density power supplies feature wide input voltage ranges from 85 to 305 Vac or 70 VDC to 430 VDC for high voltage DC-DC applications. The PBO-1 and PBO-1-B come available with single output voltages of 5 V, 9 V, 12 V, 15 V, and 24 V DC and offer 3,000 VAC input to output isolation. Both series also offer a wide operating temperature range from -40°C to +85°C at full load as well as over current and continuous short circuit protections with auto recovery.

All models further feature class II construction, carry UL 60950-1 safety approvals, and bear the CE safety mark. The PBO-1 and PBO-1-B series are available immediately with prices starting at $4.74 per unit at 100 pieces through distribution.
